The Copper Draft King chimney cover combines the decorative elegance of copper with the durable construction and functionality that are the hallmarks of HY-C Company chimney covers. A 24 gauge 100% copper hood with scalloped corners and roll-formed edges, 18 gauge expanded 100% copper mesh, 16 gauge copper-plated stainless steel base and slotted hex-head bolts make this an exceptional cap that will naturally oxidize and develop an attractive patina over time.
